I have one more thing on my mind that i've gotta say.. the balls of those guys that rolled out of Melville into the middle of an ocean, with damn near no armor on their boats, with nothing more than speed & fish, man, they had to be some of the bravest mf'ers ever!.. odds were they were gonna get theirs, but regardless, they went out and killed it!.. I have nothing but respect for ANYONE that rolled with a PT!

NW, when you get a chance, go to you-tube and search for PT Boat 623 Barge Hunting Part 1.
That will explain my reference to Final Cut. If you enjoy the first part, just play part 2 & 3 for the entire mission. All the aircraft are real and filmed at Planes of Fame in Chino, CA. Be sure to crank the volume way up.

Something I always thought was a misnomer was the sound track of PT109 when the Motor Macs are down in the engine room "winding up" the engines. I have listened to it intently and it sounds like the Hollywood sound guys used the noise that an aircraft engine starter makes. I think it is called a centrifugal starter, where you wind up a smaller motor to a great speed and then engage the main engine and the torque is enough to start the airplane engine turning over. If you have ever listened to a P51 Mustang start up that is how they sound. IRL the Packards all used a simple Bendix Starter Motor with a Solenoid just like your car. There is no high pitched whine like on an airplane. Sorry to burst your sound bubble Hollywood, but that is the truth. IRL the engine is cranked over using the starter with no spark on magnetos, until you observe oil pressure on the gage board, then you switch the Magneto Selector Switch over to "Both" and the engine coughs to life. SO it sounds like cranking a very large diesel engine to my ear.

All Packard Merlin powered P-51s used a starter motor like a car, just a whole lot bigger. I know, I worked on them. P-40s at least through the E model used inertia starters. Not sure about Allison P-51s. Real early Spitfires used Coffman starters, basically a big old shot gun blank shell, before they got starter motors. Of course we are talking Hollywood, so they could have combined sounds, until the director was pleased. The inertia starter is a lot of fun, I remember on a Harvard, the P&W 1340 failed to start, then there was a big old stack fire, while I was trying to wind her up for a second try. That may be where they got the old saying, "when seconds seem like hours!"

Hi NW, my wife and I visited the 658 back in 2011with an ENG TV camera to record the engine start-up for the 623 video which I knew I would do once the boat was finished. Well, lets just say it was less than exciting. Sorry Jerry. With the mufflers down under the water, all I heard was a lot of muffled bubbles, something like my 28 foot Bayliner used to sound like. However, for the video we spent a few days at the Desert Storm Shoot-out and Polker Run down in Jack's neighborhood at Lake Havasu City on the Colorado River. Now those babies were up to 50 feet long being trucked in from all over the country and with engines that will rattle the fillings in your teeth. I recorded several hours of sound from different boats and even managed to charm my way onto a 45 footer for a slow ride to record some really awesome slow patrol speed extended sound. All this was then cut down and edited into the PT 623 videos. There was even a 50 foot twin jet turbine there I recorded. Now that bugger wined like some snowflakes I have know. The funniest part of editing the video came when I needed the Japanese voices for the barge scenes. After finding some on the tube, I dumped them into the video and during playback, which is always very loud, I was laughing so hard my wife came in the back room to see if I was OK.

Hey Roy,
Yes I remember when you came down to see the 658. I too have tried recording the sounds that are present during the startup and operation of the engines and it is pretty difficult with wind noise etc. How did you handle eliminating the wind noise during the throttle up sequences? I was not referring to your video sound track in my comments, I was talking about PT109 movie which had the effect of convincing thousands of people how it really sounds when starting the engines on a PT boat, and happens to be completely made up! So now all those PT modelers in the world think that incorrect sound is how it should be. Also I found that the sound recorded inside the engine room sounds nothing like the sound outside the engine room when starting up the engines. Like I said before we do not use "inertial Starters" like they do on many WW2 aircraft (except for P51 Mustangs per Stearman!) I am almost positive I saw a video of them starting a P47 Thunderbolt and a FW190 and other WW2 fighters with inertial starters. One in particular there were 2 guys taking turns turning the crank on top of the cowling in order to get the inertial starter up to speed. The Packards on the PT Boats use a regular starter motor and is not as exciting of a sound like they depicted on the PT109 movie.

Frank Andruss has asked me several times to record the sounds from operating the PT658 into a handy file that can be played on model PT Boats for added realism. I just need to obtain high quality sound equipment in order to do so, and then convince the crew of how to run the boat to carry it out. My problem is that I have a hard time explaining why we need to do this to the crew.

Hey Jerry, nice hearing from you. I knew you were not referring to my boat but the sounds from the movie. Well for my sounds in the 623 video wind was not really an issue. All the recordings were done early in the morning right after breakfast and the wind on the Colorado doesn't turn on until about 11 if it's going to start blowing. As for the on-board sound, we were well under the the 150+ MPH these babies will do by maybe 140 !! I also had my back to the wind with a dead cat in hand. Now if you want some really crazy sound that did not make it on the 623 video, go on the tube and search out my other project at Apache Chief Offshore RC Powerboat and be sure to watch it past the 5:00 mark. Check out the height of that rooster tail and be sure to crank up the volume !! Maybe I could sell that sound to Frankie, ha.
